Path (brr.Brr_canvas.C2d.Path)

type t

The type for Path2D objects.

val create : unit -> t

create () is a new empty path.

val of_svg : Jstr.t -> t

of_svg p is a path from the SVG path data p.

val of_path : t -> t

of_path p is a copy of p.

val add : ?tr:Matrix4.t -> t -> t -> unit

add p ~tr p' adds path p' transformed by tr to p.

val close : t -> unit

close p closes path p.

val move_to : t -> x:float -> y:float -> unit

move_to p x y moves to (x,y).

val line_to : t -> x:float -> y:float -> unit

line_to p x y lines to (x,y).

val qcurve_to : t -> cx:float -> cy:float -> x:float -> y:float -> unit
